Answer:
79/90 0r 29/33
Step-by-step explanation:
Let 10x=8.7 and 100x=87.7
We now have two equations. Subtracting the largest from the smallest:
100x=87.7
10x=8.7
-------------
90x=79
x=7990
Hence, 0.877777...=79/90.
Hopefully this helps!
X= -5
y= -2
I didn't double check the answers by inputting them back into the equations, but if you want to then you can. Yet I am 99% positive my answer is correct.
